Abstract: For the theoretical prediction of fission product release from HTR-fuel elements the one-dimensional diffusion code SLIPPER has been developed, which describes the transport of fission products optionally by one- or two-phase diffusion. The mathematical-physical basis and general program-technical aspects are presented. The application of the code to irradiation experiments with spherical fuel elements in the Studsvik R2-reactor shows that the experimentally measured concentration profiles and fractional releases of the isotope Cesium 137 can be very well reproduced by two-phase diffusion. The used transport data for the fuel particles are in good agreement with reference values; on the other hand, the diffusion coefficients of matrix graphite are much smaller than those measured for unirradiated reference samples.
